APPARATUS FOR REFRIGERATION PLANTS.

Specification of Letters Patent.

Patented May 1, 1917..

l 0 all whom it may concern Be it known that 1, Serum THURSTEN- SEN, a citizen of the United States, residing at Louisville, county of Jefierson, and State of Kentucky, have invented certain new and useful Improvements in Apparatus for Refrigeration Plants, of which the following is a specification.

The present invention relates to an appliance known as an exhaust steam generator used for the purpose of the distillation of gas from weak and strong liquor, and is an apparatus employed in carrying on artificial refrigerating processes.

The objects of the invention are to provide an appliance in which exhaust steam will be condensed within pipes for the purpose of exchanging heat between said pipes and liquid within a drum or receptacle for gas generating purposes; to conduct the strong liquor into the drum or receptacle by means of a conduction pipe, or series of such pipes, of novel construction, whereby the strong liquor, when liberated into the receptacle, will be of a desired temperature, and whereby any gas which may form during the conduction of the rich liquor through said pipe or pipes will be permitted to pass out therefrom; to provide means for preventing the passage of any liquor out from said receptacle and into the gas pipe, due to an abnormal pressure of some sort or other being generated within the receptacle; and to seal the ends of the receptacle, so that the escapement of the steam condensation is permitted, while entrance of the exhaust steam into the condenser pipes is by means of a chamber which contains no joints in its walls and which, therefore, will be of the non-leakable variety.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings:

Figure 1 is a side view of the appliance of the present invention with the casings or drums in section;

Fig. 2 is a section on line 2-2 of Fig. 1, looking in the direction of the arrows and on a somewhat enlarged scale;

Fig. 3 is a plan view of the gas escapement box of the rich liquor inlet;

shown in Fig. 7. 1

Referring now to Fig. 1, the appliance consists of an upper receptacle or drum 9, and a lower receptacle or drum 10, which, in the construction shown, are joined together by bridge members 11, and the entire structure is supported by suitable base members 12-. The upper drum 9 consists of a body portion 13, a rear cap or closure 14, and a front cap or closure 15. The drum .10 consists of a body 16, a rear cap or closure 17, and a front cap or closure 18. The body portions and rear and front caps are of the same construction in both the drum 9 and drum 10, with the exception of a few slight variations which will hereinafter be pointed out.

The rear caps 14 and 17 each comprise a suitable dome-shaped body 19, which is provided with a tongue 20 fitting into a groove 21 in a flange 22 formed at the end of the body portions of the respective drums. As stated, these caps are the same for the drum 9 as for the drum 10, with the exception that the end piece for the drum 9 is provided with a drain 23 controlled by any suitable valvular means not shown.

The outer end caps 15 and 18 each comprise a dome shaped body 24: which is groove 26 in a flange 27 on the-forward ends of the respective drums.

The above described portions of the caps 15 and 18 are similar to the construction heretofore described in connection with the caps 1 and 17. It may be added at this point that all of the caps are joined to the flanges on the respective drum bodies by a suitable bolt or other locking means.

The caps 15 and 18 are each formed with a supplemental chambered member 28 formed with a tongue 25 seating into a formed in its interior with a cross Wall 29, thus dividing the interior thereof into an inner chamber 31 and an outer chamber 30; and this outer chamber has located therein a series of bafl'les 32 (see Figs. 5 and 6), which are arranged in radial relation about the opening 33, into which is inserted the main exhaust steam pipe.

Mounted within the cross wall 29 and communicating with the chamber 31 are a series of pipes 34 which extend longitudinally of the casing, and each of the pipes 34 is surrounded by a concentric pipe 35, leaving a space between the walls of these pipes, as will be apparent from Fig. 2. The pipes 34 terminate short of the inner terminus of thepipes 35 (see Fig. l), and the inner ends of the pipes 35 are closed and are configured to constitute a wrench receiving surface 36. These pipes 35 are threaded at their outer ends into the body of the cap pieces 15 and 18respectively, and, as shown, these pipes communicate with the chamber 31. This chamber, in turn, communicates with a passage 37, through which water of condensation passes off.

The basic principle of operation of this scheme of condensing mechanism is well known in the art. The exhaust steam enters the chamber 31, passes through the pipes 34 and discharges at the inner ends of the pipe 35 into said latter pipes. It then flows back in said pipe and eventually empties into the chamber 31 in the form of water of condensation, from whence it passes out. Of course, the steam, in passing through the pipes 34 anc 35, heat the same, thereby imparting a heating or cooling effect, as the case may be, on the liquor within the drums that is, an exchange of temperature between the pipes 35 and the liquor within the drums will take place.

Attention is called to the form of chambered member into which the exhaust steam initially enters, the walls of which are not broken by joints of any kind, and hence rendering it of a non leakable variety. Since the pressure of the steam is greatest when it initially enters, this portion of the device will be most susceptible of leakage, and should, therefore, be of a non-leakable variety.

There is a joint formed in the walls of the chamber 31, but since nothing enters this chamber but water of condensation, it is obvious that little pressure is here exerted, and leakage would not be liable to occur. Moreover, leakage of water of condensation would not be serious and would not in any wise impair the effectiveness of the apparatus.

Attention is also called to the closing of the ends of the pipes 35 in a manner to provide a wrench receiving surface 36. This is to permit of a ready extraction of any of the pipes 35 whichmay be desired. All that need be done is to apply a suitable wrench and by a turning movement unscrew the pipe from its seat within the wall of the cap 15 or 18, as the case may be.

The supplemental member 28 is bolted or secured onto the body of the cap by any suitable means, and, in the construction shown, bolt holes 38 are shown about the periphery of the member 28 (see Fig. 6), which receives bolts that pass through the abutting surface of the main body of the fteferring now to the means for conduct ing the rich liquor into the drum 9, such means comprises a pipe, or series of pipes, 39 within the drum 9, which, as will be seen from the drawings, extend in an oblique direction, with their outlet end 40 lowermost and approximately located midway of the drum 9. This pipe, or rather series of pipes, 39 connect with a box-like structure 40, shown better perhaps in Figs. 3 and 4. This box-like structure is formed with an opening 41 in its upperwall adjacent the forward end thereof, and a balfie 42 projects into a chamber 43 in said box-like structure, and prevents the entering liquor from passing outward through the opening 41.

The liquor is admitted to a chamber 44 in the rear end of the box-like structure by means of a main rich liquor supply pipe 45. Located in the chamber 44 are wing-like baffles 46 extending upon each side of the point of entrance of the pipe 45. Located also in the chamber 44 is a forward curvilinear bafl'le 47, whereby the liquor is defiected, when entering into the chamber, to the outer portions thereof, and thus an undue amount of liquor will not pass into the central of the tubes 39, but its entrance into the box-like structure will be retarded, so that a smooth and even outflow through all of the pipes 39 will be maintained.

The liquor, in passing throughthese pipes 39, will have its temperature exchanged or modified, so that, when it enters the interior of the drum 9, it will be at the same temperature as the strong liquor already within said drum, and this will produce the best gas generation. Escapement is provided for the gases which are generated within the pipes 39 during the passage of the rich liquor therethrough, by way of the opening 41, said gases rising and. passing backward in said pipes and out through the opening 41 to the upper portion of the drum.

An opening 48 is provided at the upper portion of the drum 9, and this opening communicates with a pipe 49 which at its lower end communicates with an opening 50, which opens into the lower portion of the drum 10. After the generation has taken place within the drum 9, the liquor flows through the pipe 49 and into the drum 10 where a second gen eration takes place, the liquor being finally withdrawn through an outlet opening 51 in the drum 10.

A pipe 52 is provided for conducting the gas to a proper place, a branch 53 leads from the drum 10 to this pipe, and a branch 5 leads from the drum 9 to this pipe. Owing to the pressure within these drums, frequent difliculty has arisen by reason of said pressure forcing liquid into the gas pipe which materially impedes and interferes with the proper flow of the gas therethrough. In order to prevent such flow of liquor into said gas pipe, I employ perforated pipes or check members 55, which are located within each of the branches leading to said gas pipe. These pipes or check members are shown better perhaps in Figs. 7 and 8 and consist of a tubular body 56 having its forward end 57 closed and having its rear end 58 threaded, whereby it can be attached within the said branch pipes. This tubular body is provided with elongated narrow slots 59 of a width which permits of the easy passage of the gas thcreinto, but in case liquid should reach said check or pipe members, the open ings or slots 59 will be scaled up and prevent the passage of the liquid therethrough. Of course, after theliquid has receded, the film or seal, which has been formed in the slots 59, would be broken by the pressure of the incoming gas and would allow such gas to readily pass thercthrough.

It is understood that the invention is not limited to use of exhaust steam for the purpose of supplying heat to the generator, but that steam at any pressure might be used and the same purpose accomplished.
